Animations are not working after parenting objects

Hi everyone! I am creating a Unity 2D Animation and I have the following problem. My creature have a head object, and this is the parent of the eye, nose and ear. I already have animations for these children objects (eye, nose, ear), but I had to move my head object into a dumie/empty object (in order to have two pivot points) and now my animations for the eye, nose and ear don't work. Is there any solution for this problem or I have to recreate every animation?

Hopefully not... Thanks a lot!
